I have a laptop, usually connected to a separated screen, but when I brought the laptop to work and turned it on, the screen was opening as it was still with the other monitor connected, and was all black. I managed to open:
Administrator: X:\windows\system32\cmd.exe
I need to reset my monitor settings, but I do not know the command to do it, can anyone please help me?
